In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 PowerColor 1GB Edition are significantly better than the AMD Radeon R7 250E.

The HD 6870 has a 100 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon R7 250E. This results in the HD 6870 providing 24.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6870 has a 100 MHz higher core clock speed and 16 more Render Output Units than the Radeon R7 250E. This results in the HD 6870 providing 16 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250E was released over a year more recently than the HD 6870, and so the Radeon R7 250E is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6870.

The Radeon R7 250E and the Radeon HD 6870 PowerColor 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 6870 has 62.4 GB/sec greater memory bandwidth than the Radeon R7 250E, which means that the memory performance of the HD 6870 is much better than the Radeon R7 250E.

The Radeon R7 250E has 512 Shader Processing Units and the Radeon HD 6870 PowerColor 1GB Edition has 1120. However, the actual shader performance of the Radeon R7 250E is 348 and the actual shader performance of the HD 6870 is 504. The HD 6870 having 156 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6870 delivers a massively smoother and more efficient experience when processing graphical data than the Radeon R7 250E.

The Radeon R7 250E transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the Radeon R7 250E is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon R7 250E requires 55 Watts to run but there is no entry for the Radeon HD 6870 PowerColor 1GB Edition. We would recommend a PSU with at least 400 Watts for the Radeon R7 250E and a PSU with at least 500 Watts for the HD 6870. The HD 6870 has been recommended a PSU with 100 Watts more than the Radeon R7 250E. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the Radeon R7 250E.

GPU Mini Review

Mini ReviewOverview
Radeon R7 250E is a Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU Codenamed Cape Verde PRO which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 800MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1125MHz.

Power Consumption
With a rated board TDP of 55W, it requires at least a 400W PSU and relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon R7 250E is a direct rebrand of Radeon HD 7750 and performs exactly like it.

System Suggestions
Radeon R7 250E is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.
Radeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
